Is is possible to match a group of files in alphabetic order using
globbing in csh? For example my dir looks like this:
able david greedy jolly .....
baker emery handy kape .....
cain frank intro lemma .....
I want to cat all files > george (lexicographically).
Maybe something like [g-z]* but that only looks at the first
letter and allows something like gary.
Can anyone help me please?

Hmm. Not in csh. But with a little assist from Perl: cat `ls | perl -ne 'print if $_ gt "george"'` Or, doing it all in Perl (catting and everything): perl -e '@ARGV = grep($_ gt "george",<*>); while (<>) { print; }' Just another Perl hacker, -- /=Randal L.

Now I would like to generalize it using an alias. I tried alias mycat "cat `ls | sed '1,/\!*/d'` | less" but it didn't work.

Using the "makealias" and "quote" aliases by Dan Bernstein (brnstnd@nyu.edu):
% makealias mycat
cat `ls | sed '1,/!*/d'` | less
alias mycat 'cat `ls | sed '\''1,/\!*/d'\''` | less'
I typed the "makealias mycat" command and the line starting with "cat", and
got back an alias with all of the quoting correctly done. That line is what
you would use to define the alias.
And here are Dan's aliases, in case you want to do this again with something
else:
alias quote "/bin/sed 's/\\!/\\\\\!/g' | /bin/sed 's/'\\\''/'\\\'\\\\\\\'\\\''/g' | /bin/sed 's/^/'\''/' | /bin/sed 's/"\$"/'\''/'"
alias makealias "quote | /bin/sed 's/^/alias \!:1 /' \!:2*"
Pretty gross, but they do the job....
